ASH-SIFTING ATTACI-ILIENT FOR STOVES.

Application filed May 1'2, 1922. serial No. 560,368.

To all whom t may concern:

Be it known that BRUCE C. ROBINSON and JOHN S. COLLINS, citizens of the United States of America, residing at Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in Ash-Sifti ng Attachments for Stoves, of which the following is a specification.

The object of the invention is to provide a simple and efficient ash sifting mechanism for use in connection with stoves and like hea-ting devices particularly designed for domestic use as a means of separating the ashes from the cinders prior to removal from the heating apparatus and of subsequently and separately removing the cinders for subsequent use or for assorting; and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein z- Figure 1 is a vertical sectional view of a sifting apparatus embodying the invention applied in the operative position to a stove of the domestic heater type.

Figure 2 is a horizontal sectional view of the same on the plane indicated by the line 2-2 of Figure l.

Figure 3 is a detail view of the sifter carv rier or fork.

The sifter consists of a box or frame 10 having a screen bottom 11, which is fitted in the ash pit 12 of a stove beneath the fire grate 13 and is mounted for sliding' movement upon supporting fingers 14 which are preferably of cross-sectionally angular construction to present an upwardly directed edge affording no substantial lodgmem; for ashes or cinders.

Reciprocably mounted in the suitable guide 15 in a wall of the ash pit is a shaker rod 16 having a tongue 17 for engagement with the sifter, and connected with the outer end of the shaker bar is a hand lever 18 fulcrumed as at 19 upon the frame of the stove and adapted to be oscillated lto convey a reciprocatory or shaking' movement to the sifter with the ash pit in a closed condition to the end that the loose ashes may be detached from the cinders and deposited in the bottom of the ash pit. After the completion of this separating .operation the sifter tray may be bodily removed with its contents from the ash pit, upon ythe displace- Vment of a suitable dooror closure 20, by

means of a carrier or fork shown in detail in Figure 3 and consisting of a handle 21 provided' with prongs 22 forv arrangement beneath the tray and a hook 23 for engagement with the edge of the front wall of said tray. i Y

Thus the separation of the ashes from the cinders may be effected without causing the distribution of the dust in the cellar or compartment .in which the stove is located, after which the cinders remaining in the sifter may be transported to a suitable receptacle or may be exposed for storage if there is a sufficient amount of unconsumed fuel therein to warrant such action, while the 'fine ashes may be removed from the ash pit separately and under conditions providing against the entrance thereof into the heat circulating Conductors of the stem.

Having vdescribed. the invention, what is claimed as new and useful is z- 1. A stove having its ash pit provided with supporting guides and a sifter reciprocably mounted upon said guides beneath the stove grate, and operating means including a hand lever disposed eXteriorly of the stove and connected with said sifter, said guides consisting of cross sectional angular fingers projecting from opposite walls of the ash pitrand disposed in overlapping relation with the bottom wall of the sifter. 2. A stove having its ash pit provided -with supporting guides and a sifter reciprocably mounted upon said guides beneath the stove grate, and operating means including a hand lever disposed eXteriorly of the stove and connected with said sifter, a shaker bar being reciprocably mounted in a guide of the side wall of the ash pit for actuation bysaid lever, said shaker bar, in-

terior to the ash pit, being formed with an upturned terminal tongue engaged through the bottom wall of the sifter.

In testimony whereof they affix their signatures. i BRUCE C. ROBINSON.

JOHN S.` COLLINS.
